Spaghetti Squash & Chicken Bake

Spaghetti squash is one of our very vegetables to eat in the fall.  We recently purchased an Instant Pot and used it for the first time to cook the spaghetti squash.  It turned out perfectly tender.  We separately cooked the chicken and mushrooms in a skillet and then added in the sour cream, cream cheese and spices. Lastly we combined the spaghetti squash and chicken mixture in a bowl before placing in an 8 by 8 baking dish. We roped with some fresh Parmesan and put it in the oven to bake for 15 minutes.  The girls loved this meal as the chicken came out tender and moist.  Anything with noodles is fun and exciting for them to eat.  Swapping the noodles for spaghetti squash is an added health benefit. Once again, we are able to get in some extra vegetables.
